GOVERNOR FOR EXPLOS'IVE-ENGINES.

Specicaton of Letters Patent. v Patented NOV. 17 1914.

Application filed November 1, 1913. Serial No, 798,618.

1-'0 au 'whom it may concern.'

Bev it known that I, CLAUDE SiNTz, a citizen of the United States ofAmerica, -re-' siding at `Detroit, in the countyv of layne and State ofMichigan, have invented certain new and useful Improvements in Govlernors for Explosion-Engines, of which the following-is a'specification, reference being hadtherein to the accompanying drawings.vMy inventionlrelates -togovernors for eI;-v

plosion engines and has among the objects vthereof to provide a simpleand eliicient oonstruction for adjusting the governor valve, and toprovide-a device in which the proper seating of the valve will at alltimes be insured.

Other objects of the invention will more fullyghereinafter appear.

The invention resides in the peculiar construction, arrangement andcombination of parts as hereinafter vset forth and as parf ticularlypointed out in the claims. In the draWings,-I1`igure l is a sectionalside elevation of the device embodying the invention; Fig. 2 is asection on the line :ie-zr of Fig. l.

A designates a casing vforming a portion of the induction conduitleading to the en;

gine, B the inlet therefor, and C the outlet.

D is the valve seat composed'of a cylindricalinember eltendingtransversely of thel casing A' and having the opposite ends there- 0fseated in bearings E F in the, casing. This valve seat is 4provided witha plurality of slots H in the upper side thereof, and with correspondingslots I -in the lower side,

providing a l'ilurality of spaced segmental portions (i. The valve J isarranged in the cylindrical member Dfor longitudinal slid.`

ing movement, and` is composed of a member having a plurality of spacedcircular sections l''correspoi'iding in number to the slots I-l and eachof a width slightly greater than these slots. lvl/hen the valve is openthe parts are as vshown in Fig. l, but when the valve is adjustedlongitudinally the slots H Will be'lmore or less restrctei'l, orcon'ipletely closed, according to the adjustment 'of the valve-as willbe readily understood.

The .shifting of the Valve is controlled by a centrifugal governorcomposed of arms L M arranged at substantially diametrica'llyoppositepoints upon'a sleeveN.

are springs connecting the Weightedends.

P and tending to hold the Weightedl ends at their inward position ofadjustment, 'inthe usual manner. The sleeve N is journaled up'on anextension Q ofthecasing A and is provided Wit-ha sprocket R which isdriven 1n any suitable manner from vthe crank sha-ft.

S '1s a longitudinally shiftable shaft slidably arranged Within a bore Tin the extension Q and carrying at its outer end a thrust 'bearing Uengaged by the ends V of the centrifugal arms. 'The inner end W of theshaft -S abuts against the inner end of the' valve J.

The opposite end of the casing from the centrifugal governor is providedwith a head A which closes the outer end .B of the valve D. This head.is provided with a bean.,r

ing C Within which is arranged. for longitudina-l sliding' movement ashaft D5," the inner end of which abuts against the outer end of thevalve J. v

E is a lever pivoted at F to an arm G suitably mounted. upon the vcasingA, 'and this lever has vthe end F2 thereof engagin the outer headed endofi-G2 of the shaftD Connected-to the opposite end` H of the leve!i E isa Sp1-in -f I that tends to move the lower end F2 oA the lever Einwardly and thereby exerts a yield-ing pressure upon the shaft D',tending to move the latter in a direction to maintain the 'valve open.

lVith thecon'struction so far described, when the speed of the enginebecomes too great, the gmfernor arms I will be thrown outward bycentrifugal action, since vasbefore stated, the sleeve N is driven from.the

The outward increment of the crank shaft. governor arms will more theshaft Slongitudinally inward, which will shift the valve to vnriably`restrict the ports Il, thereby restricting the flow 'of gases throughthe casing A. filon the "speed of theengine decreases so that thesin-ing 0 of thel governor arnlsinoves the latter inward, the.

spring I will act upon the'shaft H- through tlie medium of the lever Eto move the valve in the opposite direction. The speed at which th'egovernor arms are thrown out- "1' meansfof an adjusting bolt JA", whichhas a vthreaded engagement. with a. ixedbearing '1K' eveneens @emmene'tette spring 1 Thus by'adjusting the bolt J "7' the tensionof thespring I" may-be varied, and

i fi gino@ `the centrifugal; arms must'move the valve againstthe-'tensionjof the s ring I',

"this willfincrease the force require to 1iio i r a 4 '4 thegovernor-arms outwardly. By this'mam,

I suctioiircreated in the casing A during the working ofthe engine willdraw the valve upwa l y against the segments GrA in the ,uppeiiiiortbnof the 'valve seat, and therevalve and will also reduce the wear betweenthe valve and its seat to a having the yielding, meansv which op theaction of the 'overnor arranged atl-.thefopposite end 'of t e valve fromthe f -centrifugal governor mechanism, this yielding means willvautomatically take up any wear in the governor parts and thereby insuregreater aecuracvyujn the operation of the valve and avoiding what isgenerally known las back lashing of the parte.A
